If you replace the rotors, always replace the pads. The old ones are seated to the old rotor faces and can give you shudder, noise and the like. If you're savvy, it's not to hard to do. Have the right tools, be methodical, keep things clean. Don't know what the Brembo rotors go for. I guess you should have an idea about that by now. Also, don't know anything about your mech skills. Replacing rotors is not a difficult job, but it does require some knowledge of disc brake systems. If you have ABS, be careful with the sensors mounted behind the rotors. Good Luck...BTW what's wrong with the stock grippers? My 300's have more than enough stopping power with the stock MBZ brakes.
